Very nice wooded climb

A very quiet and pleasant road. On the Chambéry side, a good part is in the shade, the slope of the main road is rather constant around 7-8%. On the Novalaise side, the mineral aspect with the cliff is more present in the middle of the climb. This side is quite steep with kilometers at 8-9%. On each side, 1 belvedere offers a breathtaking view of Lake Aiguebelette (approx. 2 km from the summit) and on the other side of Chambéry, the Bauges, Belledonne, the Chartreuse (500 m from the summit). The summit is in the forest.

The lookout is too overgrown. You can hardly see the lake anymore! What a shame!

Pass without too much traffic. Quite steep start to reach Saint Sulpice, the rest is rather regular. The pass is closed in winter
